Medbery Standard Material.
The accompanying cut illustrates the standard straight line insulator, with Medbery insulation, manufactured by the Fiberite company and sold in Chicago by the Mason Electric Equipment company. The particular advantages of
this insulator exist in the fact of its being in one piece and in the insulation being thoroughly covered by the bronze casting. This makes the complete device practically indestructible, and enables the company to sell under an absolute guarantee. The Fiberite company furnishes two improved clamps or the solder ear, either one of which can be used with its standard material.
